K49229034 : Sudo vulnerabilities CVE-2014-9680, CVE-2016-7032, CVE-2016-7076, and CVE-2016-7077

Security Advisory Description

• CVE-2014-9680

sudo before 1.8.12 does not ensure that the TZ environment variable is associated with a zoneinfo file, which allows local users to open arbitrary files for read access (but not view file contents) by running a program within an sudo session, as demonstrated by interfering with terminal output, discarding kernel-log messages, or repositioning tape drives.

• CVE-2016-7032

sudo_noexec.so in Sudo before 1.8.15 on Linux might allow local users to bypass intended noexec command restrictions via an application that calls the (1) system or (2) popen function.

• CVE-2016-7076

sudo before version 1.8.18p1 is vulnerable to a bypass in the sudo noexec restriction if application run via sudo executed wordexp() C library function with a user supplied argument. A local user permitted to run such application via sudo with noexec restriction could possibly use this flaw to execute arbitrary commands with elevated privileges.

• CVE-2016-7077

foreman before 1.14.0 is vulnerable to an information leak. It was found that Foreman form helper does not authorize options for associated objects. Unauthorized user can see names of such objects if their count is less than 6.
